For tiling a terrace or around a swimming pool, the method remains essentially the same as for indoor installation, except that all the materials are not adapted to the vagaries of the weather. So be careful to educate yourself when purchasing your tiles. In addition, the work must absolutely be carried out in accordance with the rules to guarantee the sustainability of the installation. It is also recommended to tackle it in mid-season in order to preserve the joints from extreme temperatures.
Laying outdoor tiles: preparing for installation
First, make sure that the existing support is perfectly resistant, but also regular, clean and dry. Otherwise, you will have to get rid of the dirt and / or smooth and smooth it by making a leveling, even a screed in cement mortar, or even a reinforced concrete slab. Note that a slight outward inclination remains essential to allow water infiltration to be evacuated effectively. Then, we proceed to the layout, to determine the number of necessary tiles, as well as their arrangement.
The laying of tiles for the exterior
Then, using a notched trowel, spread a special exterior adhesive mortar on the floor, as well as on the back of the tiles. We can then position them, taking care to reserve a space for the joints. These can be applied after a minimum of one day, with products corresponding to the type of tiling chosen. Care should also be taken to leave a space at the bottom of the walls, where the expansion joints will then be made. To cut the tiles, it may be useful to have an electric tile cutter that will make your work much easier. Finally, to reinforce an area greater than 40 m², it is advisable to place fractionation joints of 5 or 6 mm wide minimum, at regular intervals.
